From 621ce2339ca2d657237d0a0ad34f2905ecc284d7 Mon Sep 17 00:00:00 2001 From: Alexandru Vasile <60601340+lexnv@users.noreply.github.com> Date: Thu, 28 Sep 2023 20:19:27 +0300 Subject: [PATCH] rpc/client: Propagate `rpc_methods` method to reported methods (#1713) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The PR exposes the `rpc_methods` name in the `rpc_methods` response. This feature is useful for servers that only forward requests to methods that are reported by the `rpc_methods`. Jsonrpsee exposes the available methods registered so far. Registering the `rpc_methods` requires a closure that already stores the result. As such, the `rpc_methods` method name is manually added to the available methods. Closes: https://github.com/paritytech/polkadot-sdk/issues/1627 ### Testing Done ``` $> curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "rpc_methods", "params":[]}' http://localhost:9944 {"jsonrpc":"2.0","result":{"methods":["account_nextIndex",... "rpc_methods",..."unsubscribe_newHead"]},"id":1}⏎ ``` @paritytech/subxt-team --------- Signed-off-by: Alexandru Vasile --- substrate/client/rpc-servers/src/lib.rs | 2 ++ 1 file changed, 2 insertions(+) diff --git a/substrate/client/rpc-servers/src/lib.rs b/substrate/client/rpc-servers/src/lib.rs index 92b31937a0cbb..dc625c3d6c4cf 100644 --- a/substrate/client/rpc-servers/src/lib.rs +++ b/substrate/client/rpc-servers/src/lib.rs @@ -145,6 +145,8 @@ fn hosts_filtering(enabled: bool, addrs: &[SocketAddr]) -> AllowHosts { fn build_rpc_api(mut rpc_api: RpcModule) -> RpcModule { let mut available_methods = rpc_api.method_names().collect::>(); + // The "rpc_methods" is defined below and we want it to be part of the reported methods. + available_methods.push("rpc_methods"); available_methods.sort(); rpc_api
